Hi Roger,
As these products are not available Down Under could you
please supply the following info (via SEN if necessary ) in relation to both
Mica film and Fibre film.
1) Fax/Email address of suppliers (preferably with credit card facilities).
2) Colour availability.
3) Minimum order quantities/size of roll.
Thankyou
Phil Mitchell
Turn opening by F1B
===================
Author : j.w.bourdonnay
Our best F1B man in France, Albert Koppitz, has the same problem P.
King noticed in SEN 404. At the end of the cruise the model tends to
the left, and sometimes stalls in turbulence. - If we assume that the
wing works very close to its glide attack, then the memory of an old
misfortune can be helpful. In 1981 Jean-Claude Neglais tests a new
wing, solid balsa, rectangle + tappered tip, aspect ratio 15 or so,
wing airfoil like 5406. A safe glide turn is impossible ! Always the
model ends in a straight glide path. All usual means are failing :
turbulators, CG shift, various incidence of one half wing, as well as
the TE flapped up in the tappered area. At last a paper sheet is glued
on the underside of both tips, so the undercamber fully disappears.
Now the turn is OK... in spite of the theoretical drag of a 9% thick
airfoil and reduced RN. - The cause of the problem was obvious :
a too great an angle at the beginning of the underside, in the
tappered region where progressively the local lift (and the angle
of attack) is reduced to zero. In fact exactly the same airfoil was
used from root to tip of the wing : a mistake. - Before WW2
the wings often ended in a symmetrical NACA 0006 or so. -
Perhaps our F1Bs sometimes have a too great a tip camber ?

Science Olympiad Assistance
===========================
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.
I have been assisting Science Olympiad students for two years with good
results nationwide. To keep from having to repeat my instructions to
everyone who e-mails me, I have written a 30 page handbook which details
how to build a very competitive Science Olympiad model. The book
includes a 50% plan and a complete supplier listing for all materials.
The book is $10 post-paid and may be ordered from me direct. Gary

Does anyone have for sale, a power panel cut in half to fit in an F1C-style
starter box, or a panel suitable for such mutilation?
